Just checked, reinstalled both, Spartan first and Troy second, and got the same issue.

Nope. I DID change the installation path for the Spartan (Installed Troy before that) since I assumed it should work when in the same master folder - but it didn't work in either situations (had it installed directly to Program Files before that).

As in the title. They are installed in the same "main" folder (Slitherine -> GoT/Spartan), but GoT was unable to detect the scenarios. Why might that be the case?
